The Copeland Scroll compressor inside a Rheem heat pump is the same workhorse that is used in Rheem air conditioners all around the world! The simple design of the Copeland Scroll compressor builds in reliability and allows it to operate at lower sound and vibration levels than reciprocating compressors. In fact, tests have shown that Scroll compressors are up to three times quieter than reciprocating models. Durability is based on a very robust design and contains only a few moving parts. Because the Copeland Scroll Compressor starts unloaded, strain on the motor is considerably reduced. During rough operating conditions, spiral components within the unit reposition themselves to protect the compressor from damage. Millions of air conditioners can't be wrong…the performance of a Copeland Scroll compressor gets better with time: it "wears in," not out.
